Source of mysterious Fast Radio Bursts finally identified
Scientists have finally pinpointed the source of mysterious celestial events called Fast Radio Bursts. The strong pulse of radio waves lasting just millisecond was identified coming from an elliptical galaxy six billion light years away -- half way across the universe and back through time.
Van Allen Radiation Belts are even stranger than imagined
New data indicates the Earth’s Van Allen Radiation Belts could be very different in shape from what scientists have always thought. It seems the shape of the belts depends on what type of electron you’re looking at.
Giant gas cloud explains galaxy’s missing “star forming” hydrogen
Astronomers have discovered a spectacular plume of gas more than 300,000 light-years across streaming like the tail of a comet from a bright strange looking spiral galaxy. The massive hydrogen cloud is five times longer than the galaxy itself.
Engineers working on new type of polar orbit
Scientists are working to perfect a new type of satellite orbit which can keep a spacecraft above the north or south pole. The research is looking at how a satellite equipped with a large solar sail could partly offset gravity from both the Earth and the Sun with the slight but steady pressure of sunlight, allowing the spacecraft to hover above the Arctic or Antarctic, enabling continuous coverage of high-latitude regions for science and climate observation or for regional communication services.
